I thought it was resistance that causes heating in an electric circuit but apparently not.

Moving electrons have energy. As the electrons move from one point to another, they can do work. In an incandescent light bulb, for example, the energy of the electrons is used to create heat, and the heat in turn creates light. In an electric motor, the energy in the electrons creates a magnetic field, and this field can interact with other magnets (through magnetic attraction and repulsion) to create motion. Each electrical appliance harnesses the energy of electrons in some way to create a useful side effect.

Yes it is. That's where the heat comes from. You may also get some loss due to heating a transformer core but it's primarily resistance.

Current and Resistance

The heat is caused from atoms and charges moving, colliding, and bouncing off one another as current is forced through a resistance. It is like friction.

Presence of Resistance.

I always thought it was the resistance as well. What leads you to say that it is not resistance?

i think the flowing of the electrons will change the energy of the betray from chemically to eclectically and heat...
